There's plenty of sushi ranges between 100 yen plate kaiten sushi and $300 omakase. The sushi quality bar is higher in Japan all around (maybe except for kula sushi which can still be fun but isn't going to win awards based on their fish). I personally like Hana Maru which is a Hokkaido sushi chain for good fish ordered piece by piece Kaiten-sushi Nemuro Hanamaru / Sushi bar Siki Hanamaru They have a multi-lingual menu- write down the number of the fish based on the menu, and "sumimasen!" hand the slip to the chef. They didn't even look at my partner weird after 4 orders of fatty tuna.

Try od_sf option #3 - go high end omakase once to get an idea of what high end sushi in Tokyo is like. You might find another fish to love or you'll find that maybe omakase isn't quite for you. Then for a different meal, go with a mid-end sushi option that allows you to order what you like to eat. I'm not saying the quality is the same but it is totally possible to enjoy both. Or you'll be able to funnel all the cost savings from not loving omakase towards lots of your 6 favorites
